Hello Student
Correct answer is 2. Oxygen removal
The root nodiles of legume contains enzyme nitrogenase and leghaemoglobin. Nitrogenase is highly sensitive to the molecular oxygen and requires that ensure that the enzyme is pretected from oxygen to protect these enzyme the nodule contains an oxygen scavenger called leghaemeglobin

(B)  OXYGEN  REMOVAL
 
In plants colonised by Rhizobium, such as alfalfa or soyabeansthe presence of oxygen in the root nodules would reduce the activity of the oxygen-sensitive nitrogenase, which is an enzyme responsible for the fixation of atmospheric nitrogen. Leghemoglobin buffers the concentration of free oxygen in the cytoplasm of infected plant cells to ensure the proper function of root nodules.  This allows an oxygen concentration that is low enough to allow nitrogenase to function, but high enough that it can provide the bacteria with oxygen for respiration.
